  • As the pressure increases, the radial load and the friction of the sealing lip increase in contact with the shaft. As with temperature, each oil seal has a recommended pressure for optimum performance. Excessive pressure causes the seals to wear more quickly and consequently have a shorter life.

  • 4. Marine industry NBR oil seals are used in ship engines, propeller shafts, and hydraulic systems.
  • Oil seals are typically made of high-quality rubber or synthetic materials, which are designed to withstand high temperatures, pressure, and friction. These seals are installed in areas where two components come together and require a barrier to prevent the leakage of oil or other fluids. The importance of oil seals can be seen in various parts of a vehicle, such as the engine, transmission, wheel bearings, and differentials.

  • In the UK, customers have a range of options for purchasing oil seals. There are several reputable UK gasket manufacturers that offer a wide selection of oil seals to meet various industrial needs.

  • In the intricate world of engineering and manufacturing, a seemingly insignificant component holds a significant role - the U-shaped rubber gasket. This humble piece, often overlooked, is an indispensable element in various industries, from automotive to plumbing, electronics, and even aerospace.
  • 3. Temperature limitations While high temperature rubber gaskets can withstand extreme temperatures, they may not be suitable for use in extremely low temperatures.
  • Another popular type of oil seal is the mechanical seal, which consists of two sliding surfaces that are pressed together to form a seal. Mechanical seals are known for their durability and reliability, making them ideal for high-pressure and high-speed applications. These seals are commonly used in pumps, compressors, and fluid handling equipment.
